We use one that = we call the "click-stick" as you not only have a wink to judge, it also = gives a little click when the hammer shank winks. Just move it along as = you work. It's never too long to fit any section.

For those of you who use Bill Spurlock's grand letoff jig, this should = sound familiar. Every upright has a built in let-off jig: the hammer = rail. Today I was playing with a Hallet-Davis (Pearl River version) = that's about 3 years old. It needed let-off regulation in a bad way, so = I experimented with the hammer rest rail. On this particular piano, I = could push it far enough forward so the hammers were close to the = strings, even ON the strings. Some pianos won't allow for that much = movement, but this one did. =20 I set a some samples for letoff, then pushed the rail forward to the = point where those hammers would wink when I depressed the key. I = blocked the rail so it stayed there, then adjusted the let-off to make = the hammers wink. Worked like a charm. =20 Pianos that won't allow for such free motion of the hammer rail may = require something to clamp onto the rail for the shanks to rest on--the = Spurlock jig comes immediately to mind. Hope this helps someone in some small way!
